Abstract

Detection of the consumption of hashish and marijuana in body fluids (blood, urine, sweat or saliva) is claimed (no further details). Also claimed is the detection of consumption of hashish and marijuana in breath, using a test tube with an indicator that turns red, when a user exhales into the tube. This is especially for the use of the police who are controlling traffic (no further details).

Description

Beschreibung des bekannten Standes der TechnikDescription of the known prior art

Drogen stellen im Straßenverkehr ein Problem dar. Trotzdem können drogenberauschte Fahrer sorgloser am Steuer sitzen als alkoholisierte, denn es gibt bisher keine Routinetests zum Nachweis des Drogenkonsums bei Verkehrskontrollen, keine anerkannten Grenz­ werte. Die meisten Drogenkonsumenten nehmen die in einigen Bundesländern zum Eigenbedarf freigegebenen Cannabis-Produkte Haschisch und Marihuana. Nach dem bisherigen Stand der Technik können nur Speziallabors Drogen in Blut-, Urin-, Speichel-, Haarwurzelproben oder im Schweiß nachweisen.Drugs are a problem in traffic Drivers are more carefree at the wheel than drunk drivers, because there are no routine tests to date as evidence of drug use during traffic controls, no recognized limits values. Most drug users in some states take them for their own use released cannabis products hashish and marijuana. According to the current state of the art, only special laboratories can use drugs in blood, urine, Detect saliva, hair roots or sweat.

Nachteile des bekannten Standes der TechnikDisadvantages of the known prior art

Der Nachweis von Cannabis-Produkten in o.g. Proben ist sehr kostenaufwendig. Die entnommenen Proben lassen sich nur in einem Speziallabor untersuchen, welche nicht überall vorhanden sind, d. h. der Nachweis des Cannabis-Konsums am Steuer kann nicht unmittelbar vor Ort geschehen. Ein Testgerät zum Nachweis von Cannabis-Konsum in Schweißproben ist sehr teuer.The detection of cannabis products in the above Sampling is very expensive. The samples taken can only be examined in a special laboratory, which cannot are everywhere, d. H. Proof of cannabis use at the wheel cannot happen immediately on site. A test device for detecting cannabis use in sweat samples is very expensive.

Aufgaben der ErfindungObjects of the invention

Der Erfindung liegt die Aufgabe zugrunde, bei Verdacht auf Cannabis-Konsum am Steuer einen Sofortnachweis durchzuführen.The invention is based on the object, if cannabis consumption is suspected at the wheel to carry out an immediate verification.

Lösung der AufgabeSolution to the task

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Cancolor-Schnelltest aus einem Glas- oder Kunststoffröhrchen (5 cm lang, 1 cm Durchmesser) mit Mundstück besteht. In dem Röhrchen befinden sich der Indikator mit einer Trägersubstanz sowie einem Katalysator. This object is achieved in that the Cancolor rapid test a glass or plastic tube (5 cm long, 1 cm diameter) with a mouthpiece consists. The indicator with a carrier substance and a are in the tube Catalyst.  

Vorteile der ErfindungAdvantages of the invention

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß bei Verdacht auf Cannabis-Konsum im Straßenverkehr keine Proben von Blut, Urin, Speichel oder Haar­ wurzeln entnommen werden müssen. Der Schnelltest läßt sich vor Ort, ohne technischen Aufwand, mit geringen Kosten sowie in kurzer Zeit, ohne große Schulung der Polizei­ beamten durchführen. Der Beamte kann sofort feststellen, ob der Verkehrsteilnehmer Cannabis-Produkte konsumiert hat und danach notwendige Schritte einleiten. Ein Polizeibeamter kann dieses Teströhrchen, aufgrund bei seiner geringen Größe, bei Verkehrskontrollen ständig bei sich tragen sowie sicher und leicht anwenden.The advantages achieved by the invention are, in particular, that if there are suspicions Cannabis use in traffic no samples of blood, urine, saliva or hair roots must be removed. The quick test can be done on site without technical Effort, with low costs and in a short time, without major police training perform officials. The official can immediately determine whether the road user Has consumed cannabis products and then take necessary steps. A police officer can use this test tube due to its small size Always carry traffic controls with you and use them safely and easily.

Beschreibung der ErfindungDescription of the invention

Der Cancolor-Schnelltest beruht auf einer chemischen Reaktion des Indikators mit der ausgeatmeten Luft des verdächtigen Verkehrsteilnehmers.The Cancolor rapid test is based on a chemical reaction between the indicator and the exhaled air of the suspect road user.

Im genannten Glasröhrchen mit Mundstück befinden sich der Indikator Echtblausalz B auf einer Trägersubstanz aus Kieselgel (3-5 mm Körnung).The indicator real blue salt B is located in the glass tube with mouthpiece a carrier substance made of silica gel (3-5 mm grain size).

Ein Zusatz von festen, zerriebenen Natriumhydroxid erleichtert die chemische Reaktion, welche im alkalischen Milieu effektiver verläuft. Chemisch gesehen reagiert das Echt­ blausalz-B-Kation mit dem Hauptinhaltsstoff der Cannabis-Produkte, dem Tetra­ hydrocannibol (THC), zu einem Azofarbstoff. Die in der ausgeatmeten Luft enthaltene Feuchtigkeit löst den Indikator und führt zu einem Farbumschlag. Hat der verdächtige Verkehrsteilnehmer Cannabis-Produkte konsumiert und mehrmals in das Teströhrchen geblasen, färbt sich der Indikator rot. The addition of solid, ground sodium hydroxide facilitates the chemical reaction, which runs more effectively in an alkaline environment. Chemically speaking, the real reacts Blue salt B cation with the main ingredient of cannabis products, the tetra hydrocannibol (THC), to an azo dye. The contained in the exhaled air Moisture loosens the indicator and leads to a color change. Has the suspect Road users consumed cannabis products and put them into the test tube several times blown, the indicator turns red.  

Das Teströhrchen zum Cancolor-Schnelltest haben drei Schüler des Gymnasiums Ascaneum Aschersleben im Rahmen des Wettbewerbs "Jugend forscht" unter Anleitung ihres Chemielehrers, Herrn Topf, entwickelt.The test tube for the Cancolor rapid test has three students from the Ascaneum high school Aschersleben as part of the "Jugend forscht" competition under the guidance of her Chemistry teacher, Mr. Topf.

Da nach dem Betäubungsmittelgesetz keine Experimente mit Drogen durchgeführt werden dürfen, hat die Gruppe, wie in Forschungen üblich, einen Ersatzstoff verwendet. Ein geeigneter Ersatzstoff für THC ist Phenol, da es eine ähnliche Struktur wie THC besitzt. Chemische Grundlagen, wie Reaktionsmechanismus und Reaktionsgleichungen wurden von der Gruppe erarbeitet und liegen jederzeit zur Einsichtnahme in unserem Gymnasium bzw. am Stand beim Wettbewerb "Jugend forscht" in Sachsen-Anhalt vor.Since no experiments with drugs are carried out under the Narcotics Act as usual in research, the group used a substitute. A suitable substitute for THC is phenol, since it has a structure similar to THC. Chemical basics such as the reaction mechanism and reaction equations were developed by developed by the group and are available for inspection at any time in our high school or at the booth at the "Jugend forscht" competition in Saxony-Anhalt.
